DEVICE FOR REGULATING THE FLOW OF LIQUID FROM NURSING-BOTTLES.

Specification of Letters Patent.

Patented Apr. 25, 1911.

Application led August 5, 1909. Serial No. 511,416.

Toall 'whom 'it 'may concern:

Be it known that I, WILLIAM MAO- GLASHAN, a citizen of the UnitedStates, residingat Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in Devices forRegulating the Flow of Liquid from Nursing-Bottles, of which thefollowing is a specification, reference being had therein to theaccompanying drawing.

My invention relates to improvements in a device for regulating the Howof liquid from a nursing bottle.

The object of my invention is to provide an attachment of this characterwhich can be applied to the ordinary nursing bottle and the nippleapplied whereby the How of liquid from the bottle is regulated, and saidregulating means adapted to be operated by the turning of the nipplewithout removing the nipple from the bottle.

Another obj ect of my invention is to provide a more simple, cheap'A andeffective device to accomplish these results.

Figure 1 is a vertical sectional view of an ordinary nursing bottle withthe nipple applied and showing my device applied in the mouth of thebottle. Fig. 2 is a top plan view of my improved device. Fig. 8 is aperspective view of the stopper showing more fully the cam arrangementfor raising the valve. Fig. 4 is a detached view of the spring forholding the valve seated. Fig. 5 is a vertical sectional view similar toFig. 1, of a modified form of my device. Fig. 6 is a vertical sectionalview similar to Fig. 1,

and showing a still further modified form of device.

Referring now to the drawings, l represents the upper neck of anordinary nurs- .ing bottle having the usual flange 2 for retaining thenipple'S thereon. Within the mouth of the bottle, I propose to place myimproved regulating device, and it consists of a stopper 4, which is ofan elongated sleeve-like form having the inner face reduced at its lowerend 5 forming a valveseat 6. This stopper is of a diameter considerablyless than that of the mouth of the bottle, and in order to form a tightjoint between the stopper and the mouth of the bottle, I place a rubbergasket or ring 7. This gasket or ring being of a'crcular form incross-section, allows the stopper to be placed in bottles havingdifferent sized mouths, the gasket expanding to fit the mouth. The outerend of the stopper 4, is provided with an annular Hange 8 resting uponthe upper end of the mouth of the bottle. The outer edge of the flange 8is provided with an annular raised cam face 9, having a series ofcircular depressions 10 therein.

Fitting within the sleeve-like stopper 4 is a valve 11, having the innerwall reduced at its lower end 12, adapted to form a tight joint with thevalve seat 6, and the extreme lower end of the valve extending below thelower end of the stopper 4. The valve is provided with verticallyarranged passages 11 and 12 through which the liquid passes from thebottle. This extended end is provided with an enlarged head 13, adaptedto carry the spring 14, which bears against the lower end of the stopper4, and normally holds the valve 11 in its seated or closed position. Inorder that the valve may be readily removed, the spring 14 is providedwith a keyhole slot 15, whereby it is readily removed or attached to thevalve. For Vthe purpose of lightening the valve, I have prefc rably madeit of a hollow form, but if desired, it may be made solid. The upper endof the valve 11 is provided with an umbrellaflange 16, the outer edge 17extending out 1n a vertical alinement with the outer edge of the Hange2, of the bottle. By this structure it will be seen that the nipple 3 ofthe bottle rests upon this Hange 16 and the turning of the nipple 4onthe bottle turnsthe Harige and raises or lowers the valve 11, as willnow be described.

The flange 16 is preferably formed with a series of large openings 18and a second series of smaller openings 19 for reducing the weight ofthe flange. The metal of this flange 17 is turned downwardly at 20within one of the openings and bears upon the cam surface 9, of' theHange 8. This downwardly turned portion or tongue 20 has its lower endrounded and adapted to rest in one of the recesses 10 in the cam-face.

By the above description, it will be seen that by turnin the nipple onthe neck of the bottle the ange 16 is turned with the nipple as it has alarge engagement therewith. This causes the tongue 20 to travel upwardlyon the cam face 9 of the Harige 8 and raising the contracted end 12 ofthe valve from the seat '6, and allowing the liquid to pass u wardlyaround the valve 11 into the nipp e, the tongue 20 holding the valve inits adjusted position by entering one of the depressions or recesses 10.The spring 14 when the valve is in this position has been Compressed andfurther aids in holding the valve in its adjusted position. By turningthe nipple in t-he opposite direction to that just described, the tongue20 travels down the cam-face 9 of the fla-nge 8, the spring lcausing thevalve 11 to seat itself upon the seat 6 of the stopper and thus cuttingoff the vlio-w of liquid from the stopper. This arrangement allows thevalve to be s'oadjusted that any desired amount of liquid can flowthrough the stopper as necessity inay require.

lhile I have shown and described this specific form of regulating means,it will be understood that I do not care to limit myself to the same asnumerous other forms of valves can be used without departing from myinvention, such as are shown in Figs. 5 and 6 of the drawings.

In the modification shown in Fig. 5, the stopper 4 instead of having thecam face, has at its lower end extensions 21 and 22 upon which isvertically adjustable a nut 2B, and the lower end of the valve 11 isprovided with a screw-threaded extension 24v screwed into the nut 23.The umbre-llafiange 16 is operated by a nipple in the same manner as isshown and described in Fig. 1, and thus by turning the flange 16 thevalve is screwed up and down within the nut 28, causing it to seat andunseat itself, as is clearly shown in the drawings. In order to preventthe umbrella fiange 16 from being accidentally turned the lower facethereof adjacent to its outer edge is provided with recesses 25, inwhich rests a spring member 26 carriedby the ange 8 of the stopper. Thisarrangement allows of the ready turning of the umbrella-flange 16, yetprevents it from being accidentally turned.

In the modification shown in Fig. 6, I use an ordinary stopper 27, of anelongated form and preferably of rubber tightly fitting within the monthof the bottle. This stopper has a central opening 28 through which asleeve 29 passes forming a tight joint therein. This sleeve has acontracted lower end 30 forming a valve seat 31. Above the valve seat 31the sleeve is internally threaded at 32. Fitting within the sleeve 28 isa valve 33 having a screw-threaded connection with the sleeve. The lowerend of the valve is contracted and tightly fits the `seat 31 of thesleeve. The valve is provided on opposite sides with vertically arrangedpassages 34 and 35, through which 'the liquid passes from the bottle.The umbrella-flange 16 is constructed the same as in Fig. 1, and isprovided with recesses 25 and the spring member 26 working in the samemanner, as shown in Fig. 5.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:
